Kai's verdictS-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.A-tier. Bet on this one — the Sparkpage format is genuinely new.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for academic research. Nothing else comes close for systematic reviews.
